Midea Cube 50-Pint vs Midea Cube 20-Pint
Both wear the same stackable Cube shell and both talk to Wi-Fi and Alexa, but they are built for very different jobs. The 50-Pint (with pump) is our best-overall pick for a whole basement; the 20-Pint is a small smart unit for one damp room. Here is where the roughly $90 gap actually goes.
| Midea Cube 50-Pint (Pump + Wi-Fi) | Midea Cube 20-Pint | |
|---|---|---|
| Overall score | 7.4/10 | 3.3/10 |
| Moisture removal | 50 pints/day | 20 pints/day |
| Coverage | 4,500 sq ft | 1,500 sq ft |
| Noise | 45 dBA | 45 dBA |
| Power draw | 512 W | 262 W |
| Built-in pump | Yes | No |
| Wi-Fi / app | Yes | Yes |
| Tank | 4.25 gal | 3.2 gal |
| Typical price | $280 | $190 |
Capacity and coverage: not the same class
This is the headline difference. The 50-Pint pulls 50 pints a day and is rated for 4,500 sq ft, so it can dry out a full basement, crawl space or musty lower level. The 20-Pint moves 20 pints a day across 1,500 sq ft, sized for a single bedroom, bath or closet. Our engine scores moisture removal 9 for the 50 and just 4 for the 20. If your problem is whole-home humidity, mold or a persistent musty smell, the smaller Cube simply cannot keep up no matter how long it runs.
Efficiency, pump and drainage
The 50-Pint is Energy Star Most Efficient and scores 7 on efficiency; the 20-Pint scores just 1, our worst in the catalog, drawing 262 W to remove less than half the water. The bigger unit also adds a built-in pump, so it can push condensate up and out to a sink or window for true set-and-forget draining, plus a 4.25-gallon extendable tank. The 20-Pint has a large 3.2-gallon tank but no pump, so gravity drain or manual emptying is your only option once it fills.
Noise, size and price
On paper both list 45 dBA, but the 20-Pint's real-world measured level is closer to 58 dBA, while the 50-Pint holds nearer its rating; the engine scores both a 4 for quiet, so neither is a library. The trade-offs are physical and financial: the 20-Pint is lighter at 33 lb and cheaper at about $190, versus 41.5 lb and roughly $280 for the 50-Pint with pump. You pay the premium for capacity, efficiency and hands-off drainage, not for a quieter or smaller footprint.
Verdict
For a basement, whole-home humidity or any real mold and musty-smell problem, the Midea Cube 50-Pint (pump + Wi-Fi) is the clear winner and our best-overall pick — far more capacity, much better efficiency, and self-draining via its pump. Only choose the 20-Pint if you are treating one small room, want to spend about $90 less, and value the lighter, more portable body over performance.
